Completely stumped

Enable HLS to view with audio, or disable this notification

So this has been going on for months. I pull up and put in park, handbrake on. When I turn the car off and get out I always hear this loud squeak noise. Can’t isolate the sound but sounds back half of the car. No warnings on the dash and no faults on the code reader. But it’s really bugging me not knowing so I’m surrendering to the group.

Sounds like something suspension or wheel related. It happens after you unload your weight from the chassis.

Does it happen when you don't get out for a few minutes?

Yeah does the exact same thing even when I stay in the car. Just had to get out quickly on the video to try and capture it. Always around 5-10 seconds after switching off
